I have no idea, i removed all that by getting into the recovery mode with the adb loop. I'm guessing you should be able to boot to clockwork recovery mode and then adb shell into that. I'm not 100% sure. Give it a try, the worst thing that can happen is it doesn't work and you'll need to do the loop.bat/sd card timing trick to get back into it to remove the files, which isn't that bad but hopefully this will bypass that. Let me know what you find, i'd be interested to find out myself.
